This new environment has different resources and different competitors, so the new population will need different features or adaptations to be a strong competitor than what they had needed before. Here is the same text in Swahili:
Mazingira haya mapya yana rasilimali tofauti na washindani tofauti, kwa hivyo idadi mpya ya watu itahitaji vipengele au mazoea tofauti ili kuwa washindani imara kuliko walichohitaji awali.
